Product overview
Double-sided Tape Adhesive GJ-8000 series is a solvent-based pressure-sensitive adhesive range for the production of double-sided tapes on foam, PET and sponge-paper carriers. Fifteen grades are available, each tuned for a property that tape converters specify: high temperature resistance, weather and anti-warping resistance, extra high adhesion, retention, low VOC, single-liquid processing, transparency or water solubility. Solid content runs from 30% to 50% and viscosity from 1500 to 15000 CPS at 23 °C.
Core industrial grades include GJ-8055 (50% solids, 5000~10000 CPS), a high-temperature-resistant adhesive with good late viscosity and punching performance for foam, PET and sponge-paper tapes used in electronics and computer accessories; GJ-8020 (48%, 7000~13000 CPS), which bonds aluminum plate, PP board and glass at low temperature while retaining 80 °C heat resistance; GJ-8059K (40%, 1500~4000 CPS), an extra-high-adhesion grade for thin PET that withstands 200 °C; and GJ08019 (32%), whose retention lets a foam tape hang 10 kg.
Single-liquid foam grades GJ-8120D, GJ-8155D, GJ-8116D and GJ-8131D are weather-resistant, anti-warping adhesives for foam substrates, with GJ-8131D wetting EPDM and other refractory foams. Specialty grades cover low-VOC automotive tape (GJ-8022), ultra-narrow foam frames (GJ-8017), graphite cooling film (GJ-8023), substrate-free transparent PSA for nameplates and solar glass (GJ-8078), water-soluble environmental labels (GJ-8095) and the universal grade GJ-8045. ChemPortal supplies all grades in wholesale quantities.

Frequently asked questions
Which GJ-8000 grade should I choose for foam tape?
For general foam tape, GJ-8055 and GJ-8155D suit foam, PET and sponge-paper carriers with good punching and blanking. GJ-8120D, GJ-8116D and GJ-8131D are single-liquid, weather-resistant, anti-warping foam adhesives, GJ-8131D for EPDM and other refractory foams, and GJ-8017 is made for ultra-narrow foam frame fixing.
What temperature resistance do these adhesives offer?
GJ-8059K withstands 200 °C and is intended for thin PET with strong surface adhesion. GJ-8020 and GJ-8120D bond at low temperature and retain performance at 80 °C. GJ-8055 is the high-temperature grade for foam, PET and sponge-paper tapes, and GJ-8022 adds superior temperature, water, weather and chemical resistance for automotive tapes.
What are the solid content and viscosity ranges across the series?
Solid content ranges from 30% (GJ-8078) to 50% (GJ-8055, GJ-8058, GJ-8155D), and viscosity from 1500~4000 CPS (GJ-8059K) up to 6000~15000 CPS (GJ-8022), all measured at 23 °C. The technical data sheet gives the individual value for each of the 15 grades.
